Thank you, Peter. I would expect some brood kill. I believe the
recommended rate from Finland that I've used with excellent results
is 4 ml per bee space (the Greek study used 5 ml) but perhaps this
difference does not affect the results much. I would also apply only
one treatment - has been very effective for me and I've read repeated
treatments can cause queen problems. Perhaps this explains the Greek
observations of 4 months of brood problems.
I have a couple of other options. Treat with sucrocide which I did
not find effective 2 years ago (and I thought I saw decreased brood
rearing). Or wait until November and treat then. It would be useful
to see how the bees from my queen cope with varroa pressure...
